Quantum many-body scars from virtual entangled pairs
Sambuddha Chattopadhyay, Hannes Pichler, Mikhail D. Lukin +1
We study weak ergodicity breaking in a one-dimensional, nonintegrable spin-1 XY model. We construct for it an exact, highly excited eigenstate, which despite its large energy densi…
Parallel implementation of high-fidelity multi-qubit gates with neutral atoms
Harry Levine, Alexander Keesling, Giulia Semeghini +8
We report the implementation of universal two- and three-qubit entangling gates on neutral atom qubits encoded in long-lived hyperfine ground states. The gates are mediated by exci…
One-way quantum repeater based on near-deterministic photon-emitter interfaces
Johannes Borregaard, Hannes Pichler, Tim Schöder +3
We propose a novel one-way quantum repeater architecture based on photonic tree-cluster states. Encoding a qubit in a photonic tree-cluster protects the information from transmissi…
Emerging 2D Gauge theories in Rydberg configurable arrays
A. Celi, B. Vermersch, O. Viyuela +3
Solving strongly coupled gauge theories in two or three spatial dimensions is of fundamental importance in several areas of physics ranging from high-energy physics to condensed ma…
Generation and manipulation of Schrödinger cat states in Rydberg atom arrays
Ahmed Omran, Harry Levine, Alexander Keesling +16
Quantum entanglement involving coherent superpositions of macroscopically distinct states is among the most striking features of quantum theory, but its realization is challenging,…
Quantum Metasurfaces
Rivka Bekenstein, Igor Pikovski, Hannes Pichler +3
Metasurfaces mold the flow of classical light waves by engineering sub-wavelength patterns from dielectric or metallic thin films. We describe and analyze a method in which quantum…
Quantum acousto-optic control of light-matter interactions in nanophotonic networks
G. Calajo, M. J. A. Schuetz, H. Pichler +4
We analyze the coupling of atoms or atom-like emitters to nanophotonic waveguides in the presence of propagating acoustic waves. Specifically, we show that strong index modulations…
